Vedolizumab Compared with Certolizumab in the Therapy of Crohn Disease: A Systematic Review and Indirect Comparison

Objectives The increasing prevalence of Crohn disease (CD) underscores the need to identify new effective drugs, which is particularly important for patients who do not respond or do not tolerate standard biologic therapies. The purpose of this analysis was to compare the efficacy and safety of vedolizumab and certolizumab pegol in patients with active moderate to severe CD. Methods This analysis was prepared according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. A systematic literature search of Medline (PubMed), Embase, and the Cochrane Library was conducted through March 5, 2016. Studies included were randomized controlled trials (RCTs) that enrolled patients treated for CD with vedolizumab or certolizumab pegol. All studies were critically appraised; indirect comparison was performed with the Bucher method. Results Eight RCTs were identified, and four were homogeneous enough to be included in the indirect comparison of the induction phase of treatment. No statistically significant differences were found in clinical response (relative risk [RR] 1.23, 95% confidence interval [CI] 0.81–1.88) or remission (RR 1.35, 95% CI 0.89–2.07) between vedolizumab and certolizumab pegol in the overall population. Similar nonstatistically significant differences in response and remission were noted in a subgroup analysis of anti‐tumor necrosis factor‐naive patients (RR 1.10, 95% CI 0.72–1.66 and RR 1.98, 95% CI 0.95–4.11, respectively). In addition, there were no statistically significant differences in safety profiles. Conclusions This indirect comparison analysis demonstrated no statistically significant differences in efficacy and safety between vedolizumab and certolizumab pegol.
